Doorway standard. Types of interior doors: materials and standard sizes. About standard sizes

If you do not want to overpay 20-50 percent for non-standard interior doors, then you need to decide on the doorway in advance.

You need to start from the doors you like, the variety of which can satisfy even the most fastidious taste. Basically, doors are produced in standard sizes: 2 meters high and 60, 70, and 80 cm wide.

Helpful information:

Less common is a standard with a width of 40, 55 and 90 cm and a height of 1.9 meters. The thickness of the door frames can vary in the range of 1.5-4 cm.

Table of standard opening sizes

Depending on the room, standard door sizes may be used.

This is how they usually put it:

• in the bathroom and toilet, the height of the opening is usually from 1.9 to 2 meters, width 55-60 cm, depth 5-7 cm.
• in the kitchen height 2 meters, width 70 cm, depth 7 cm.
• in the bedroom or living room, the height of the doorway will be 2 meters, width 80 cm and depth from 7 cm to 20 cm.
• if the door to the bedroom has double doors, then only the width will change: it will be either 2*60 cm, or 40+80 cm.

After plastering and leveling the walls, the depth of the doorway will increase accordingly.

These dimensions of doorways are very difficult to overestimate. After all, if you did not take them into account in your calculations, you may encounter a problem when your door frame does not fit into the opening. And not every opening can be enlarged; sometimes this is impossible due to the specific layout or design of the wall. If this is a load-bearing wall, then you will also face a number of difficulties.

Even a simple plasterboard wall is not easy to reduce due to the transfer of metal profiles. In this case, you will have to overpay for non-standard sizes of the interior door.

There is also the opposite situation, when the doorway is much larger than the door. Here you will also overpay specialists when installing the door, for narrowing the opening.

An unpleasant situation may arise when, as a result of reduction, the platband cannot close the hole in the doorway. In this case, you will need to seal up the uncovered sections of the wall, glue wallpaper or lay tiles. It’s good if the room hasn’t been glued up yet, but if it has been, then everything will have to be re-glued.

Therefore, even at the project stage, you need to decide on the size of the doorways, then you won’t have to overpay for non-standard doors or redo the opening.

What you need to know to calculate a doorway:

• height and width of the proposed door
• door frame thickness
• box width
• width of platbands
• the box will be with or without a threshold.

Suppose you need a door measuring 2 by 0.8 meters and 2.5 cm thick. To calculate the dimensions of the doorway, you need to add the dimensions of the frame to the dimensions of the door, plus an installation gap of 1 to 2 cm on each side.

Figure y shows a diagram of a doorway with a door and dimensions. Using these data, we can easily obtain the opening width of 800+30+30+10+10+4+2=886 mm or 88.6 cm.

You can find out the width of the frame on the website of the manufacturer of the doors you like.

• with a threshold of 2000+30+30+10+5+3=2078 mm. or 2 meters and 7.8 cm..
• without threshold 2000+30+10+5+3=2048 mm. or 2 meters and 4.8 cm..

Please note that the most common thickness is 7.5 cm and therefore many manufacturers adhere to this particular size.

If the wall is thicker or thinner than the box, then you will need to install an extension or cut the box lengthwise, respectively. Without these operations you will not be able to and everything will look much worse.

When renovating, it is necessary to pay due attention to the installation of interior doors. Of course, there are certain standard dimensions, but in order not to have to destroy the wall or change the already chosen canvas, it is necessary to study all the nuances. In this matter, it is important to correctly calculate the dimensions of the opening, know the standard and features of different types of structures. On the modern market you can find domestic and foreign products; it is important to remember that GOST standards are different.

GOST sheet size indicators

The parameters of the door leaf must be taken into account when calculating the opening. Doors and frames have standard sizes approved by the state.
GOST table of interior paintings:

If repair work was previously carried out, the walls were leveled or dismantled, the depth may not correspond to the above data.

The market offers a large selection of doors and components from domestic and foreign manufacturers. Most often, products have a height of 200 cm, a width of 60, 70, 80 cm (less often 190 by 60, 70.80 cm). The thickness of the door frame starts from 15 mm and up to 45 mm. Knowing the standards and dimensions of the doorway, you can choose the best option. There are situations when ignoring the parameters ends with the expansion of the opening or the return of the newly purchased canvas.

When purchasing canvas from a foreign company, you need to carefully study the dimensions because their standard is somewhat different.

Doorway measurement formula

If you need to make an opening, but the issue with the door has not yet been resolved, you need to take into account the following points in advance:

• Dimensions of the canvas: height and width, thickness.
• Door frame dimensions: width and thickness.
• Width of platbands.

Calculation example:

• Tight

Height (H) – 200 cm

Width (W d) –70 cm

• Box

Thickness (T k) – 3 cm

• Installation gap (Mz) -1 cm

Door block (BD) – 2 cm

• Threshold height (in p) – 2 cm

Formula for calculating the width of a doorway:

W dv +2*T k+Mz+2*Bd = 70+2*3+1+2*2=81 cm

Formula for calculating the height of the opening:

V dv + V p +2*T k= 200+2+2*3=208

Conclusion: for a door leaf 200 by 70, a doorway of 208 by 81 is required.

Opening depth: standard 7.5 cm, so manufacturers make door frames to fit this size. If the canvas has already been purchased: you will have to make a box individually, or wider - use an extension. Therefore, it is better to carry out calculations in advance.

Algorithm for measuring the size of a doorway

To correctly measure the size of the opening, you must follow the following sequence of actions:

• Measure the height from the floor to the top (if the opening is not level, you need to measure in the narrowing area), to the middle of the casing.
• Width – from the middle of the left to the middle of the right casing (taking into account the narrowing).
• Depth is measured at the top, middle and bottom (to find the widest measurement).

A positive result depends on the accuracy of the measurements.

Standard doorway calculation table:

Parameters of the frame and door leaf

The dimensions of the interior door frame must correspond to the dimensions of the door leaf, taking into account the gaps.

The frame should be proportional to the thickness of the wall. If there is free space left, add-ons are used to cover the gaps.

Extensions are racks around the perimeter of the frame to expand the door frame.

The main element remains the doors themselves. The standard is determined based on the following parameters:

• Interior door leaf height: 190-200 cm. Sometimes an individual approach is necessary. When making calculations, it is necessary to take into account the gap between the base and the floor so that the canvas opens and closes freely.
• The width depends on the room.
• Thickness varies (depending on the manufacturer’s requirements), standard is 4.5.

Features of double doors

For the living room, a good solution in interior design would be to install double-leaf interior doors. Attention, when calculating the dimensions, double the values.

As for GOST: the standard is a width from 120 to 150 cm. This range allows you to get a convenient, complete and functional design. Thickness – 4.5 cm.

Details about measurement and installation:

If the opening does not correspond to the specified size and cannot be expanded, the following is necessary:

• One leaf is in a fixed position and is used as needed.
• The width of this leaf is 1/2 or 1/3 of the width of a standard interior door.
• The second is a full-fledged door.

Both options have a big advantage in functionality: they improve maneuverability: it’s easy to bring in and take out furniture.

As for the height: if the opening is larger than the specified standards (size: 200-210 cm), a special fixed bar is attached at the top.

Maximum canvas dimensions

The widest standard doors are 90 cm. Only a limited number of manufacturers produce products of such dimensions. In new buildings, such parameters for the interior door frame are not used, because the design looks ridiculous or cumbersome. Still, these sizes are found:

• In the "Stalin"
• In offices.

The most popular material for interior dimensional (and not only) canvases: MDF.

There is probably little that can be changed in renovating the interior of an apartment or private house without causing global devastation and without spending significant effort or financial resources so that it has such a practical and aesthetic effect as if you change the interior doors.

After all, no matter how beautiful the wallpaper or flooring is, when leaving the room, the last thing that fixes our consciousness is the decor and quality of the panel (canvas) with its frame. Therefore, such a final touch largely influences our perception of the design and comfort of the room as a whole.

Marking of door products

With the marking, which is the passport of the product, not everything is so simple. On the one hand, there are certain GOST designation recommendations, and on the other, the abundance of manufacturers sometimes creates confusion in the general standards. It is not uncommon that doors manufactured using the same technologies and having visual identity can be named and labeled in different ways.

First, let's look at the state standard, which no one has canceled. Thus, the production of wooden internal doors for residential and public buildings is still valid GOST 6629-88, according to which it is indicated (in order of positions in the marking):

Product type: D- door assembly, P- door leaf.

Fabric type: G- deaf, ABOUT- glazed, TO- glazed swinging, U- reinforced with continuous filling.

Height of the door with frame, in dm.

Width of door with frame, in dm. Additional letter indices: L- left door, N- with floating, P- with a threshold.

State standard index.

For example: DG20-10L GOST 6629-88 or PO19-7LN GOST 6629-88.

Despite the fact that any self-respecting manufacturer of door products still adheres to state standards, along with official model designations, entrances and individual factory codes. For example, one of the Russian brands uses such identification, producing doors 40 mm thick and 2000 mm high:

Model name.

Type of canvas. DG- deaf, DOF- with milled glass, DOOF- with two milled glasses.

Opening width, cm.

Veneer color.

Opening direction.

For a version of such products, you can read on the packaging: "Stella" DG 60 Oak lion.

Ultimately, no matter how different any factory marking is from the Gost marking, what is more important to us is the appearance, structure and operational properties of the door, about which you will need to ask the seller in detail and carefully study the company passport attached to each product with its characteristics and installation instructions.

The market does not allow you to relax in search of a suitable model, offering a seemingly huge variety of door products. However, upon closer examination, several main types of products can be distinguished:

For painting

Allows you to achieve a complete color combination with the surrounding design. Supplied primed, completely ready to be coated with decorative interior compositions.

In this group of products, two subtypes should be distinguished - elite and budget oriented. The expensive segment of doors for painting is produced for the so-called hidden installation. After installing and tinting such a product, only a protruding handle can indicate the presence of a passage in the wall.

Budget models can be found in many public institutions; they are also widely used in “economy” apartment renovations and as temporary options. They are a textured MDF coating on a timber frame. Their main advantage is the lowest price among all door designs.

Laminated

They are delivered to the retail chain ready for installation. In many ways, the design is reminiscent of the previous budget class. However, they have a stain-resistant coating laminated with a polymer film that can imitate any decorative material.

They can be filled with heat and sound insulating materials: corrugated cardboard, mineral wool, polyurethane foam or polystyrene foam. There are models with smooth or textured surfaces, as well as with profiled overlays made of pressed MDF.

Veneered

They are the next, higher level in quality and appearance. The basis for them is the same frame MDF with different types of fillers. The thinnest sections (0.7 mm) of valuable wood - veneer - are glued onto the base, which are then varnished. The result is a complete imitation of a product made from massive material, but with less weight and an affordable price.

Made from solid wood

You probably shouldn’t once again praise products made from all-natural materials. In addition to all its advantages, such a door will add sophistication and comfort to any interior, if you are willing to pay its high cost. However, one should not forget that wood is very sensitive to changes in humidity, therefore, for the long service of such elite products, mandatory control of the indoor microclimate is required.

Glass

They also belong to the high price segment of the market offerings of door products. They help in the implementation of special design delights, and are also ideal for installation at the entrances to bathrooms, showers, saunas and other places with high humidity. They come in transparent, translucent, matte, colored glass and with surface milling.

Metal-plastic

They serve as a good solution for exits to loggias, terraces, as well as for damp rooms, as a cheap alternative to glass doors. They have excellent sound insulation and heat retention qualities. The surfaces of products can be laminated with films to match any natural material

About dimensions and more. Standard sizes of interior doors

If we do not take into account the non-standard approaches of some private customers, for whom the binding of door dimensions is based on subjective requests and desires, then most manufacturers are guided by standard openings of typical buildings from the Soviet period. And why reinvent the wheel - from the point of view of the ergonomics of door products designed for the physiology of the human body, everything has long been invented and thought out.

At the same time, the share of individual requests (regarding product sizes) on the market is small, and therefore is successfully filled by the efforts of small private manufacturers, although they are much more expensive than standard models.

The ratio of the sizes of doorways and doors (door frame + leaf) according to domestic SNiP. From the tables below you can find out the size of the doorway for a door with a width of, for example, 80 cm.

The ratio defined by the DIN standard:

Width

First of all, when talking about the size of doors, both swing and sliding, any of us means the width of the door that we will use every day. In some places you need and want a wider one, but in others a narrow alignment is enough. Gostov's proven recommendations offer the following parameters:

For bathrooms - 600 mm,

For kitchens - 700 mm,

For living rooms - 800 mm.

If we consider real market products, then their range (adjusted to the needs of modern consumers) is somewhat wider:

For bathrooms - 550 mm And 600 mm,

For kitchens - 700 mm,

For living rooms - 800 mm And 900 mm.

Let us not undeservedly forget double doors, because they often emphasize the special status of living rooms or passages to terraces. They are usually made up of the same standard fabrics in equal and unequal combinations, for example: 600+600=1200 mm or 600+800=1400 mm. Also for the “kopeck piece”, narrowed segments are used 400 mm - 400+400=800 mm or 400+800=1200 mm.

Height standards

If we start from the domestic “classics”, then they have been preserved in the proposals 1900 mm And 2000 mm, although now the European standard is also often found - 2100 mm. Higher products can also be installed - 2300 mm and even to the ceiling. It is clear that such “giants” are more convenient to use in a sliding version.

The thicker the canvas, the better?

Is it always like this? What does this parameter affect? Of course, massive thick doors perfectly highlight the interiors of living rooms, especially those made in the Empire, Baroque, and Renaissance styles, but thin screens and sliding partitions will be an excellent addition to passages to pantries or dressing rooms.

The thicker the door, the heavier it is (in its group of design solutions and type of materials), therefore, the requirements for its hinged fittings will be higher; it may be necessary to install additional hinges, which in total will lead to an increase in the cost of the entire product. Therefore, the choice of canvas based on the criterion of massiveness, as well as on other parameters, should be based on rationality and optimality.

Typical products prevailing on the market have thicknesses in a range of sizes 30-40 mm. Already in this fork of parameters, you can most often find doors 35 mm And 40 mm, as well as with intermediate values 36 mm And 38 mm.

In addition to the indicated running dimensions, sliding MDF partition doors can be very thin - from 20 mm, but products from solid wood enterprises are unlikely to be produced with a base cross-section less than 40 mm(can reach up to 50 or more on special orders). It should be noted that doors made of tempered glass, whose thickness starts from 8 mm, have come to private interiors relatively recently, but are gaining popularity.

What else is good to know when choosing an interior door?

When taking measurements of the opening to purchase a new door, keep in mind that it should be at least 30 mm larger dimensions of the box along the top edge and width. The installation gap will be required to adjust the product using wedges, followed by fixation with polyurethane foam. Of course, this value is relevant for the opening that is correct in relation to the vertical and horizontal.

Most boxes are made thick 35 mm. Those. dimensions of the width of the product assembled with the canvas 800 mm will 870 mm (+35 mm*2). Similarly, the size increases in height, although you still need to take into account whether there is or is not a threshold.

Thick doors retain heat better and counteract noise from adjacent rooms.

When installing the box, before installing the floor coverings, carefully calculate the level of the finishing surface. If the door starts to rest on the floor, then it is very difficult to trim it perfectly on your own, and this cannot be done with every model.

In conclusion, we can say that the interior door structure, despite the apparent simplicity of the device, is quite sensitive to installation errors. Therefore, either its installation and configuration will take a lot of your time, or you will have to involve highly specialized specialists.

When installing entrance and interior doors, as well as replacing them, it is necessary to take into account a lot of different factors that will affect both the installation process itself and subsequent operation. Everything is important, from the side in which the door will open to the presence of a threshold. But perhaps the most important point will be measuring and calculating the installation size of the opening.

Doorway standards

Regardless of whether the premises are being renovated or a new house or apartment is being decorated, the standard dimensions of doorways must be taken into account. The main parameters of the opening are, in principle, standardized, but many door manufacturers may deviate from the standard by a small amount. To avoid unpleasant moments that lead to an increase in the cost of repairs in general, you must know the exact size of the opening, otherwise a situation may arise when you have to order doors of a non-standard size, and this, of course, is more expensive.

Today the manufacturer will offer several standard sizes of doors and door frames. The most common door size is 2 meters in height, and the width can be 60, 70 or 80 cm. However, it is not uncommon to find ready-made doors with a height of 190 cm and a width of, for example, 550 mm. At the same time, the thickness of the door frame can be from one and a half to 5 cm.

You need to pay attention not only to this, but also to many other points that will appear when examining the doorway. local. First of all, you need to pay attention to the following things:

Knowing these nuances, you can easily select and install both interior and exterior doors.

How to calculate a doorway

Calculation and installation of the doorway. will pass without complications in the case when the box matches the dimensions of the opening as accurately as possible. If the box is significantly smaller, it is not a fact that you can securely fasten it in the opening, but it is even worse when it turns out to be larger. In principle, this is not a catastrophic situation, but you will have to either widen the opening or order new doors, which is completely useless.

To correctly calculate the size of the opening, you need to know only a few parameters. First of all, you need to know the height and width of the door leaf itself, know the thickness of the door frame and its width and the width of the trim. An example of the calculation is shown in the diagram in several versions, but for accuracy it is necessary to take into account the installation gap of at least 2 cm around the entire perimeter.

Box thickness and possible problems

Now it’s worth talking about the thickness of the door frame. In typical houses, which are built from identical panels or even brick, the wall thickness is basically standardized - it is a stable 75 mm. Based on this size, almost all manufacturers make the thickness of the door frame exactly this way. But if this is not taken into account, then you will have to install an additional expander or, conversely, saw off part of the box, which not everyone can do at home.

If you do not precisely adjust the thickness of the frame to the thickness of the walls, then installing the platband can be either difficult or completely impossible, which will certainly affect the appearance of the door group as a whole. To avoid mistakes, it is necessary to measure the thickness at at least three different points, and if the size is not too different and is within the standard, then you can do without ordering a non-standard design. Otherwise, it will either be the installation of extensions or the longitudinal sawing of the box.

Additional timber can also be useful in cases where the walls are not very pleasing with their ideal geometry, which is quite often found in panel and brick high-rise buildings. If it is not installed, then the platband, like a carbon copy, will repeat the curvature of the wall, which is undesirable, since it will spoil both the overall composition of the door and the interior of the room as a whole.

In principle, this is all that needs to be taken into account when installing a doorway and designing a door arch, but finally, the craftsmen give some advice from their own experience:

This way you can avoid mistakes and install doors quickly and efficiently without unnecessary nerves and misunderstandings. Good luck with all the repairs and quality doors!

There are a huge number of door designs for interior rooms in an apartment or cottage in terms of design, material of manufacture and opening mechanisms. Moreover, most of them are made according to GOST standards for interior doors. This greatly simplifies their selection and installation. You can, of course, install a model with non-standard dimensions in your home. However, such a product will cost more than a standard version made according to GOST.

GOST requirements for standard doorways

The dimensions of the interior door (door block) must strictly correspond to the dimensions of the opening in the wall between the rooms. In fact, it is the opening parameters that are prescribed in construction standards and GOSTs. And in accordance with them, you already have to select the thickness and width with height for the door frame and the door leaf inside.

If you are creating a unique designer interior in a private house, then the doors to the rooms can be made whatever you want. It is only necessary, at the project preparation stage, to provide openings in the partitions and load-bearing walls of the required sizes. But then door products will have to be ordered according to individual parameters for more money than standard options.

When creating an exclusive interior, do not forget that a door can complement the style if you approach the issue correctly

With city apartments the situation is fundamentally different. All of them are built according to standard design solutions, in which openings for interior doors are initially laid out to standard sizes. And in the vast majority of cases, expanding this hole is prohibited. Here it remains to select the door design only according to existing realities. And knowing the requirements of GOST, choosing a door in a store will be simpler and more error-free.

What is the door structure made of?

Marking of interior doors

When choosing an electric generator or a submersible pump for dirty water, you have to carefully study many parameters in the data sheet for this equipment. The power of the unit, productivity, and other quantities are important there. With an internal door everything is much simpler. The accompanying documentation indicates a set of numbers and letters that fully describe the width and height, as well as the design features of the product.
Based on their design and method of opening, door blocks are divided into several main types:

1. “G” is a blank wooden panel.
2. “O” – canvas with glass insert.
3. “Rp” or “Rl” – right or left swing door.
4. “K” or “P” – swinging or sliding structure.

Design options for interior doors

In addition to these letters, the marking also indicates:

• type of product - door block for the entrance to the apartment (“DV”), interior (“DM”) and for the bathroom (“DS”);
• width and height of the opening - two figures in decimeters;
• number of canvases in the block;
• class of air permeability (“B1”, “B2” or “B3”) and strength (“Md1”, “Md2”, “Md3” or “Md4”);
• designation of the standard “GOST 475–2016” (introduced to replace the old GOST 6629-88).

The above standard contains a table that lists the standard sizes of interior doors. More precisely, the reference dimensions of openings in walls and partitions are indicated there. It is these standard sizes that door block manufacturers start from. According to them, the height of the opening can be 1870, 2070 or 2370 mm, and the width from 710 to 1950 mm.

Dimensions and thickness of the canvas

The width and height of the door leaf are usually made 70 mm smaller than the dimensions of the door along the outer perimeter. 30–35 mm on each side goes to the box (frame). But there may be other options that are far from these standard values. Manufacturers are free to choose the dimensions of the product parts themselves in accordance with the design and materials from which it is made.

• for the kitchen – 70 cm;
• for the bedroom and other rooms – 80 cm;
• for the living room - double-leaf model 120 cm;
• for the bathroom – 60 cm.

Typical sizes of interior doors for different rooms

The standard height in all cases is assumed to be within the range of 1800–2000 mm, and the thickness of the canvas is 30–40 mm. At the same time, it is recommended to install doors in a bathroom or bathroom that are a little thicker and with a more moisture-resistant coating than in ordinary rooms.

How to correctly measure the height of doors with a threshold

Standard box sizes

The width of the box should ideally completely match the thickness of the wall. If the door is thicker than the interior partition, it will be difficult to secure it in the opening. Plus, there will be unsightly gaps on the sides under the casing. In the opposite situation, when the wall is too thick, you will need to install additional additional elements (extensions).

Design of interior doors with extensions

Opening sizes

Typical dimensions of doors with frames and openings for them are described in GOST standards. House designers and door block manufacturers try to follow these standards to make it easier for builders to select materials. However, often constructed buildings have deviations in height or a slight slope.

How to measure a doorway correctly

An opening for an interior door that differs from the standard dimensions in domestic high-rise buildings is far from uncommon. When measuring it before going to the store for the door block, you should measure the width and height of the existing hole in the wall in several places at once. It will still need to be leveled strictly vertically. If you make an error in the measurements, then it is unlikely that the product will be installed in accordance with building regulations.

Necessary measurements for interior doors

Double doors

If the opening is wider than 80 cm, then it is recommended to install a double door in it. The size of the door leaf is selected in such a situation as for two halves of a single structure. In rare cases, it is also possible to install a one-and-a-half model - one canvas is large, the second is half as large. But even here it is better to try to choose an option with two sliding doors. It will look more aesthetically pleasing than its one and a half counterpart.

Doors with hidden frame

Owners who want something unique in the interior often refuse standard models and prefer to install doors with a hidden frame. In these blocks, the door leaf is flush with the surface of the wall, and there are no platbands as such. The dimensions of interior doors of this design are selected according to the same scheme as ordinary ones. Only in thickness they should ideally correspond to the parameters of the interior partition, so as not to protrude from it even by a centimeter.
